1. Irregularity in the periodic maintenance of transformers, Periodic maintenance of transformers is considered one of the most essential factors for a service free from sudden failures and recurring problems.
2. Increasing loads on the electrical network, Unplanned load increases put additional pressure on transformers, which may lead to severe service damage.
3. Damage to the electrical insulation system, Different weather factors and fluctuations in temperature and humidity significantly affect the insulation system, especially oil transformers that primarily rely on oil as an insulator and coolant to dissipate heat from the transformer during its operation period.
4. The deterioration of distribution network equipment, Ensuring the compliance of network equipment specifications with the unified technical specifications of the Electricity Holding Company through the technical guide.
5. The weakness of transmission networks and the absence of control centers that transfer electricity to distribution networks and perform current regulation tasks.
